It's nonsense that stepdown or stepup transformers in general are a high end no no. There is no audible effect whatsoever if you use decent units. I run an all American system in Germany. My Wadias are fed by PSAudio PS300 which accepts 220Volts (switchable) and feeds 115-120 Volt. My AudioResearch SP14 was switched to 220Volts as was my McIntosh MC 2000(the latter with quite some fee). Revel's LE-1 was switched for no charge at the dealer's in Boston.If you use a transformer do check if you can install it it the unit's housing. It is possible in most cases. That means there's no need for an extra special powercord etc.
Good luck! And welcome in Old Europe as they say?!
